shell-and-tube heat exchangers for its heat-transfer needs. In 1994, these were replaced with five semi-welded plate heat exchangers from Alfa Laval, configured for a closed-loop cooling. They are used for cooling purification water and for cooling the reactor water. NISTs requirements on all nuclear-island equipment are particularly
bonded plate heat exchangers as well as scraped surface, tubular and ohmic heat exchangers. These cover virtually every type of duty even condensing and evaporation duties. Viscosity (cP) Scraped surface heat exchanger Tubular heat exchanger 10,000 5,000 0 0 1 10 Particle size (mm) Plate heat exchanger Alfa Laval offers a broad range of heat IWC Industrial Water Cooling Heat ExchangersAuxiliary cooling at a power generation plant, or wort cooling at a brewery, or an ammonia evaporator to produce chilled water for mineshaft cooling are all applications done by plate type heat exchangers. Plate heat exchangers are available with single, semi-welded, free flow or fully welded plates. Plates are bolted together in a plate pack with each plate sealed to the next by means of a gasket or a laser-weld. Plate and Gasket
Mar 01, 2017 · Welded plate heat exchangers provide several process and cost benefits that apply to atmospheric distillation units, hydrotreating, hydrocracking, fluid catalytic cracking, alkylation, isomerization, reforming, vacuum distillation units, sulfur-recovery units, Paraflow Plate Heat Exchangers Product Name / TitleAPV plate heat exchangers are one of the most versatile and cost-effective methods for the heating and/or cooling of fluids. The basic concept uses a corrugated heat transfer plate to separate the hot fluid from the cold and transfer the heat between the fluids. The seal between the plates is established by a peripheral gasket
Semi-welded plate heat exchanger The Alfa Laval semi-welded heat exchanger (SWPHE) alternates welded channels and traditional gasketed channels. The refrigerant flows in welded channels and the only gaskets in contact with the refrigerant are two circular porthole gaskets between the welded plate pairs. These gaskets are made from highly resistant SONDEX® Traditional plate heat exchangers DanfossSONDEX® semi-welded plate heat exchangers are the prime choice for challenging applications that involve aggressive media or high levels of pressure. We customize each heat exchanger to your specifications, and offer durable solutions designed to withstand extreme conditions and minimize the risks of operating with chemicals or refrigerants.
The semi-welded plate heat exchangers are optimized for industrial applications. The semi-welded plate heat exchangers from Danfoss is designed for ammonia systems and can be used for applications such as Condensers, flooded and pumped evaporators, Sub-coolers, Desuperheaters and Oil coolers.
